TOP CLAMP FOR UPHOLSTERY-SPRINGSL SPECIFICATION forming part of Letters Patent No. 752,169, dated February 16,1904.

Application filed April 11, 1903.

To all whom it may concern: I

Be it known that I, PHINEAS F. KING, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of 5 Ohio, have invented a certain new and useful Improvement in Top Clamps for Upholstery- Springs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

It is customary to construct upholsteringsprings in such a manner that the contactpoints of adjoining springs at their upper parts are secured together by means of clamps or fasteners and to also fasten the springs which I 5 are upon the edge of the cushion to the frame or guide wire. This has been accomplished -in numerous ways, sometimes by wrapping wire around the adjoining portions ofthe Wire springs and also by clips; but up to the date of my invention it has been quite diflicult to arrange these clamping devices in such a manner that they will not work loose and will at the same time permit the springs to give with respect to each other or with respect to the z 5 frame-wire.

It is the object of this invention therefore to provide a clamp or clip which will be so arranged that it will prevent the wire of the springs and the other parts which are con- 0 nected together by them from giving or slidmg endwise 1n any direction.

The invention may be said to consist in the construction and combination of parts hereinafter described, reference being had to the accompanying drawings, specification, and

claims.

Referring to the drawings, Figure 1 is a perspective View of my improved clamp unattached. Fig. 2 is an end view thereof, showing the clamp in position for holding the shown in Fig. 5.

Referring to the parts by letters, A represents the main flat plate portion of the clamp,

Serial No- 152,117. (No model.)

and a a two clampingfingers which are bent down from opposite ends of said flat-portion, said clamping-fingers being adapted to be bent partially around the two wires B B of the springs which are to be fastened by said clamp.

represents what may be called a separating-finger, which is integral with the plate portion A and before it is bent projects out from one side thereof. This separating-finger is bent downward substantially as shown, the line of the bend being substantially at right angles to the linein which two clampingfingers a a are bent down from the plate A.

This device is applied to the springs to fasten them together by putting the two wires against the under face of the plate A, between the two clamping-fingers a a, and with the separating-finger a between the diverging portions of said wires, as shown in the drawings. The clamping-fingers are then bent tightly over said wires, drawing them together and againstopposite edges of the interposed clamping-finger a, which is thereby caused to bite into the diverging spring-wires, and thus prevent them from sliding withrespect to each other. These clamps preferably are not placed around the springs at their contactpoint, but to one side thereof, and it is possible to so place them, because the separatingfinger is widest in the direction transverse to the axes of the wires. The result of this construction and of so placing the clamps is that the clamps are prevented from working along the wires in the direction of their divergence, because of the clamping action of the fingers a, and is prevented from working along the wires in the contrary direction by the sepa-- rating-finger a. p

In the modifications shown in Figs. 5 and 6 two of the clamps C and C'- are joined together by a flat metal portion D. The operation of the clamps themselves is substantially the same as already described. This of course makes a better construction for the meeting portions of the springs themselves rather than for the meeting portion of a spring and a frame-wire, but may be used for either.

From the disclosure it will be seen that all of the clamps present a smooth upper face for coming in contact with the upholstering.

Having described my invention, I claim 1. A top clamp for upholstering-springs consisting of a plate portion, having clampingfingers bent down from opposite ends thereof, and a separating-finger bent down from one side thereof along a line substantially at right angles to the lines over which the clampingfingers are bent down.

2. A top clamp for upholstering-springs consisting of a plate having two clamping-fingers bent down from each end thereof, and a separating-finger bent down-from each side thereof, the lines in which these separatingfingers are bent down being substantially at right angles to the lines in which the clamping-fingers are bent down.

3. A top clamp for upholstering-springs consisting of a plate having clamping-fingers bent downward from opposite ends thereof, 4

and having an integral downwardly-bent separating-finger, combined with two diverging wires lying on opposite sides of said separating-finger, and around which the clampingfingers are bent to hold them together and in contact with said separating-finger.

4. A top clamp for upholstering-springs consisting of a plate having clamping-fingers turned down from opposite ends thereof, and having a separating-finger turned down from one side thereof and adapted to lie between two diverging wires when said wires are embraced by said clamping-fingers.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
